Bio

PC Lai is Professor in the Department and Honorary Deputy Director of the Geographical/Land Information System Research Centre. She was Associate Dean of Faculty of Arts (1998-2003). Prior to joining the University, she was affiliated with Department of Geodetic Science and Surveying of the Ohio State University (1989-92) and Department of Geography of the University of Maryland at College Park (1983-89). Dr. Lai specializes in digital/geographic information systems and environmental health. She has served as a technical consultant to various public/government agencies in United States, and more recently in Thailand and for the World Health Organization.

Research Interests

Geographic Information Systems (including public and environmental health applications); cartographic modelling and spatial analyses; thematic cartography (including election, socio-economic, and tactile mapping); environmental mapping and 3D spatial display; transportation studies and network analysis.
